Appendix A. Changing the battery
Your computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as parallel-port assignments (configuration). A
battery keeps this information active when you turn off the computer.
The battery normally requires no charging or maintenance throughout its life;
however, no battery lasts forever. If the battery fails, the date, time, and
configuration information (including passwords) are lost. An error message is
displayed when you turn on the computer.
Refer to “Lithium battery notice” on page vi for information about replacing and
disposing of the battery.
To change the battery:
1. Turn off the computer and all attached devices.
2. Unplug the power cord and remove the cover. See
“Removing the cover” on page 19 (small desktop model),
“Removing the cover” on page 29 (desktop model), or
“Removing the cover” on page 41 (microtower model).
3. Locate the battery. See
“Identifying parts on the system board” on page 20 (small desktop model),
“Identifying parts on the system board” on page 30 (desktop model), or
“Identifying parts on the system board” on page 44 (microtower).
4. If necessary, remove any adapters that impede access to the battery. See
“Installing adapters” on page 22 (small desktop model),
“Installing adapters” on page 32 (desktop model), or
“Installing adapters” on page 46 (microtower model) for more information.
5. Remove the old battery.
